Neat Calculator. I am giving a shot.

Got a Evergreen hollow tube PartNo:230 to cut.

I need to have one tube joining the other at 90 degrees or at a T-junction.

I plugged in these numbers.

The cutting pattern came out looking somewhat disproportionate.
Any help would be great. Thanks.

Hello Sparky, Thank you so much for taking notice of my queries. a) The length of the wire should be just under 50 inches for 'each' LED. If constructed in parallel, the wire I need is about 2 for each LED?!?: - 2 white LEDs for the cockpit. (50 inches x 4 wires) - 4 strong white LEDs for the front ...

Someone please help to clarify this bit. Sorry if this has been mentioned a million times before. Thanks in advance. a) Does the length of the cable make any difference to the battery power required? b) Does having different color LEDs again make any different in the construction? c) Would different...

Thanks TREKKRIFFIC. That is one fine clamp. Now I know such thing exists, next step is to look around locally.

Hey big-dog, Had a quick look at HF. Not quite sure what you are trying to say.

Has anyone seen one that could clamp both a model stand (12 inches height) and onto the side of the bench, at the same time?

Umi, That is a really nice drawing. You have enormous talent. For me, I still like the good old fashion way, a pencil, ruler and french curves. So far have not been successful with any autocad software. Just find that the feeling could flow better from the arm to the pencil, then from a mouse & ...

Thanks chacal. That really helps, especially when the styrene I am using is also 1mm thick. I went away to try it this morning right after posting the question. And then wondered why it didnt work out. Now I have the answer. The 12.2mm was exactly what went wrong. :evil: Let me get back to the bench...

If I am building a rounded shape with 4cm diameter at the base and 1.8cm diameter at the top, and the distance between the two is 0.8cm, does that mean I cut round sheets of styrene from (4cm to 1.8cm) till its 0.8cm thick and then glue them all together and start sanding? Any advise would be great....

I have been thinking over it for the last 2 nights now. I think its because the shape of the internal ribs were wrong in the first place. It didnt cater for the shape required on the surface. I gamble and took some risks. I think I have to tear it open and rip out those ribs. :( I dont know how to d...

I am in quite a bit of problem both with the glue and the construction at the moment :evil: :cry:

My scratchbuild is glue on the surface half way just to find that the internal ribs shapes are forcing the surface styrene to twist in different directions.

Help please :oops: :cry: :cry:

Scratchbuild model-stand

Attempting my first scratchbuild. The overall material is acrylic sheet, hence I am considering between using a acrylic tube (perhaps diameter 2cm to 3cm) or build a square tube (2-3cm). Its confusing when I try to decide how to stick this tube to the model, as it would have to be positioned and glu...
